Wisconsin base rate
Wisconsin's statewide base sales tax rate is 5%, before local/district taxes that push the combined rate higher in many areas.
The Wisconsin sales tax rate
Wisconsin's statewide rate is 5%. Most of Wisconsin's 72 counties impose an additional 0.5% county sales tax (70 of 72 counties as of mid-2025, following Racine County joining April 1, 2025 and Manitowoc County joining January 1, 2025). Exceptions: Milwaukee County charges 0.9% (increased from 0.5% on January 1, 2024); Winnebago and Waukesha Counties had no county tax as of early 2026.
What rate do online sellers charge?
Wisconsin uses destination-style rates in most cases, so the rate you charge depends on where your buyer is — the state base of 5% plus any local/district tax at the delivery address.
You only charge Wisconsin tax once you have nexus there — physical presence or crossing $100,000 in sales.
Who collects it
On marketplace sales (Amazon, Etsy, eBay), the marketplace facilitator collects and remits Wisconsin tax for you. On your own store (Shopify, WooCommerce) you collect it yourself once you're registered.
